.15 units already installed as wellas form a component part of a newheating system; and which functions most efficiently by drawing theproducts of combustion through a series of conduits from the upper tothe lower part ofthe structure and by maintaining the products ofcombustion at a nearly'uniform high temperature during its travelthrough a series of conduits. i I

Further objects of the invention are to provide a device of the classstated, which is simple in its construction and arrangement, durable,compact, attractive in appearance, and comparatively inexpensive tomanufacture, install and operate.

Figure 5 is a fragmentary side view of the division wall,and'ofassociated parts. i Referring indetail to the drawing, 1 and 2respectively denote a pair of rectangularly I shaped andverticallydisposedend casings. Each'of the end easingsl and 2 preferably ind t pcludes a'gremoviable outer side wal 4, which may be secured in positionby means of screw's'5, or in any other suitable manner. 0 'A verticallydisposed division Wall6 extends from. the top to the bottom of each ofthe end casings 1 and 2. The space between 'thelouter sidewall 3 and thedivision wall 6 constitutes the combustion chamberl'i, which. extendsthroughout the height .of respective end casings 1 and 2. A burnerelement 8 is mounted in the'bo-ttom' offeach combustion chamber 7, andwhile these elementsas illustrated, are adapted for'gas fuel, it isappar- ..7 0 ent that the construction of'the combustion chambers andburner elements may be such as to render the same adaptable for theconsumption of coal, oilor any other fuel. f Y Y The space between'thedivision wall 6 and the inner wall 9 of each of the end casings :1 and2is divided into a plurality of separate compartments, respectivelyindicated at 10, 11, 12, 13, 14, 15 and 16 by the pair of verticallyextending partitions 17 and the plu-lso rality of horizontally disposedpartitions18. The'end' casings 1 and 2 are identical to each .otherjinconstruction except that in the I end casing thefcompartments 1'1,12'a'nd 13 are disposed at th effront, and the compartments'lt, 15 and 16 are disposed atfthe rear, 7 while inithe end casing 2 the compartments14, 15 and 16 are disposed'at the front, and the compartments 11, 12 andl3 are disposed at the rear. The compartments {1 0 constitute ling draftpassages and are disposed between the front and rear compartments, andextend throughout the heights of the latter.

The division walls 6 constitute the outer side walls of the compartmentsand the inner side walls for the combustion chambers 7. The divisionwalls 6 are preferably removably mounted in respective end casings 1 and2, and are maintained in position between the outer ed es of thepartitions 17 and 18 and a pair of fixed guides 19 provided therefor ineach of the casings 1 and 2.

A plurality of horizontally extending conductor pipes are joined withthe end casings 1 and 2 to communicate withthe respective compartments10, 11, 12, 13, 14, 15 and 16 in the following manner The conductor pipe20 connects with the top compartmentsll of the end casing 1 and with thetop compartment 14 of the endcasing 2; the conductor pipe 21 connectswith the compartment 12 of theend casing 1 and with the compartment 14of the end casing 2; the conductor pipe 22 connects with the compartment12 of the end casing 1 and with the compartment 15 of the end casing. 2;the conductor pipe 23 connects with the compartment 13 of the end casing1 and with the compartment 15 of the end casing 2;

the conductor pipe 24 connects with the compartment 13 .of the'endcasing 1 and with the compartment 16 of the end casing 2; and theconductor pipe 25 connects with the lower end of the compartment 10 ofthe end casing 1 and with the-compartment 16 of the end cas- 2- i i Inlike manner, the conductor pipe 26 connects with the top compartment 11of the end casing 2 and with the top compartment 14 of the end casing 1the conductor pipe 27 connects with thecompartinent 12 of the end casing2 and with the compartment 14 of the ,end casing'l; the conductor pipe28 connects with the compartment 12 of the end casing 2 and withthe'compartment 15 of the end casing 1; the conductor pipe 29 connectswith the compartment 13 of the end casing 2 and the compartment 15 ofthe end casing 1; the conductor 30 connects with the compartment 13 ofthe end casing 2 and with the compartment 16 of the end casing'l; andthe compartment 31 connects with the lower end of the compartment 10 ofthe end casing 2 and with the compartment 16 of the end casing 1.

p The conductor pipes 20, 21,22, 23, 24, and 25 are arranged insuperposed parallel relation to each other at the front of the structurein the sequenceenumerated, and the con- Qductor pipes 26, 27,28, 29,30and 31 are like- "tor pipes constitute radiator manifolds for theradiation of heat during the operation oftheheatingapparatus. I

A fine pipe 32 is disposed between and with parallel to the upperconductor pipes 20 and 26, and communicably connects with the upper endof the compartment 10 of the end casing 1 and with the upper end of thecompartment 10 of the end casing 2. The flue pipe 32 is provided with aneck 33 adapted for connecting with a suitable conduit leading to astack orchimney.

The division wall 6 is provided with a cut out top corner as indicatedat 34, whereby the compartments 11 of the end casings 1 and 2 have noouter wall but open directly into the combustion chambers 7 ofrespective end casings 1 and 2.

In the. end casing 1 the products of combustion will travel upwardly inthe combustion chamber 7, pass through the cut out corner 34 of thedivision wall 6 and enter the conductor pipe 20. The products ofcombustion will travel-back and forth through the front conductorpipes20, 21, 22, 2 3, 24 and 25. Upon leaving the conductor pipe 25 theprodnets of combustion travel upwardly through the compartment 10 in theend casing 1 ands bustion will travel through the rear conductor pipes26, 27, 28, 29, 30'and 31 in identically it the same manner to thatdescribed relatively to the front conductor pipes, except that theproducts of combustion will travel in the opposit'e'directions incorresponding conductor The path of travel of the products 7.

.of combustion are clearly indicated by arrows in Figures 1, 3 and 4.

A feature of the present invention is that the products of combustionare passed from the upper to the lower part .of the structure throughthe series. of conductor pipes. Ex-

tensive experimentation has conclusively proven that such arrangement ismost effective in producing the maximum ofheat on a minimum consumptionof'fu'el.

The efficiency of the structure is further enhanced by thearrangement'of the combustion chamber 7, as the inner walls 6 of thelatter constitute the outer wall of the associated compartments, and inconsequence the prod ucts of combustion in passing through the latterare subjected to intense heat andmaintained at a uniformly hightemperature until finally dissipated through the'fiue pipe 32. Byproviding two combustion chambers 7 at respective ends of the conductorpipes the heating capacity of the structure is increased many times inrespect to a structure infwhich but one combustion chamber is employed,

The compartments 10 of the end casings 1 and 2 constitute draftpassages, and as said compartments 1-0 are directly subjected'to intenseheatfrom the combustion chambers 7, draft action will be stimulated fordrawing the products of combustion through the series of conductorpipes. The products of combustion enter the top conductor pipes 20 and26 from the top of the combustion chambers 7 of respective end casings 1and tor pipes 25 and 31 into the lower ends of the compartments 10 orrespective end casings 1 and 2.

Each series of front and rear conductor pipes provides a separatecontinuous conduit from the upper end of respective combustion chambers7 to the lower end of respective compartments l0 and while suchdownward.

travel of the products of combustion is against the natural flow of thelatter, the draft action provided will cause the unretardedtravel of theproducts through the series of conductor pipes in the manner illustratedand described.

It will here be noted that the arrangement, configuration and number ofconductor pipes embodied in my improved heating apparatus may be widelyvaried to meet conditions found in practice. The structure is preferablyconstructed from sheet material of a metal best suited for heatradiation. The device may or may not be inclosed in a jacket dependingupon whether the device be utilized for local or remote heatdistribution.

The present invention provides a most efficient heating apparatus,having an exceptionally larger radiating surface, and which willfunction to produce a relatively high heating capacity on minimum fuelconsumption.
